“…This demonstrated that despite the consumption of carboxyl functionality used in the crosslinking reaction, there was still significant functionality remaining in the polymer. It also indicated a possible structural motif with at least 2 carboxylates in close proximity to each other,33–35 as seen in some oxidized sugars that also demonstrate Ca +2 ‐sequestering ability 36…”

Copolymers of citric acid and D-sorbitol were synthesized with a solventfree vacuum-oven synthesis with molar ratios of citric acid to D-sorbitol ranging from 1/1 to 6/1. The extent of the reaction was followed by the monitoring of the residual acid content of the system. As expected, the reaction occurred much more rapidly at 150 than at 110 8C. The Fourier transform infrared (FTIR) spectra of the products showed the expected FTIR bands at approximately 1735 and 1188 cm À1 , which were indicative of ester formation. Gel permeation chromatography showed a major product with a molecular weight of approximately 3500 Da. An insoluble material with a water-absorption index of up to 17 was also synthesized and could lead to possible applications as absorbers, thickeners, and biobased seed coatings. Additionally, the mono-and disodium salts of citric acid were also polymerized with D-sorbitol in a manner similar to that of the citric acid system. Soluble polymers were synthesized with a residual acid content of 5 mequiv/g of polymer. These materials showed Ca þ2sequestering ability (up to 0.56 mmol of Ca þ2 /g of the product).

“…179 These sugar acids may be oxidized to aldaric acids to form FDCA and the salts of aldaric acids and be used in numerous processes such as plastic polymers, fabrics, nylon, carpet fibers, de-rusting, paint stripping of metals, tanning hides, concrete additives, and corrosion inhibitors. 188,189 Mannitol is a natural polyol product that can make up a relatively large fraction of the biomass (up to 8% DW) in Nannochloropsis, 102 the majority of which would end up in the soluble liquor fraction during the conversion process, 3 and thus recovering mannitol as a slipstream might have economic benefits. Sorbitol, the hydrogenation product of glucose can be produced through chemical or biological hydrogenation and, together with mannitol (similar to sorbitol but with a different optical rotation) enter as a feedstock into a range of different applications.…”

“…Because hexaric acids have four stereochemically diverse secondary hydroxy groups and two carboxyl groups, they have been studied since the 1950s as platform chemicals for producing chelating agents and corrosion inhibitors [10,11,12,13,14,15,16,17,18,19,20,21], precursors for polyamides [22,23,24,25,26,27,28,29,30,31,32,33,34,35,36], polyesters [37,38,39,40,41], polyanhydrides [42], polycations [43], coordination polymers including metal–organic frameworks [44,45,46,47,48], pendant polymers [49], macromolecules [50,51], cross-linkers in hydrogels [52], medicines [8,9,10,11,49,51,53], and other compounds including platform chemicals, like adipic acid and furan dicarboxylic acid [54,55,56,57,58,59,60,61,62].…”

Sugar acids obtained by aldohexose oxidation of both the terminal aldehyde group and the hydroxy group at the other end to carboxyl groups are called hexaric acids (i.e., six-carbon aldaric acids). Because hexaric acids have four secondary hydroxy groups that are stereochemically diverse and two carboxyl groups, various applications of these acids have been studied. Conventionally, hexaric acids have been produced mainly by nitric acid oxidation of aldohexose, but full-scale commercialization has not been realized; there are many problems regarding yield, safety, environmental burden, etc. In recent years, therefore, improvements in hexaric acid production by nitric acid oxidation have been made, while new production methods, including biocatalytic methods, are actively being studied. In this paper, we summarize these production methods in addition to research on the application of hexaric acids.
